What are some good ways to identify poisonous mushrooms from non poisonous?

You should never eat a mushroom that you are not completely certain you can identify as safe to consume. Any doubt you have about the type of mushroom means you should not eat it. However, mushrooms that appear to have a toadstool shape, bulbous bottom cup, umbrella cap, or have small spores and pimples on their caps are known to be poisonous. These mushrooms should not be picked, or in some cases, touched. The Amanita muscaria is a toadstool mushroom and is very poisonous.

The Mushrooms layers coloured with black or dark is poisonous mushrooms. but the Mushrooms layers coloured with white or bright is Non-poisonous mushrooms.....
